Re: "Crack" noise on either forward or backcast
When a Bull Whip makes that cracking noise it's because the "popper" on the end of the whip is actually moving at the speed of sound. What you hear is actually a small sonic boom. You can cause the same thing to happen to the leader, tippet and of course the fly. I have broken hooks, tippets and frayed leaders being impatient about getting the forward cast going. I have found that a number of faults can be corrected by simply allowing enough time for the back cast to finish before beginning the forward stroke.
